1.6.0

This release includes the following changes since the
1.5.1 release:

• Common Library:
  • Add AudioManagerCompat and AudioFocusRequestCompat to replace the equivalent classes in androidx.media.
  • Upgrade Kotlin from 1.9.20 to 2.0.20 and use Compose Compiler Gradle plugin. Upgrade KotlinX Coroutines library from 1.8.1 to 1.9.0.
  • Remove Format.toBundle(boolean excludeMetadata) method, use Format.toBundle() instead.
  • Fix bug in SimpleBasePlayer where setting a new currentMediaItemIndex in State after setPlaylist with null MediaMetadata does not reevaluate the metadata (#1940).
  • Change SimpleBasePlayer.State access from protected to public to make it easier to handle updates in other classes(#2128).
• ExoPlayer:
  • Add MediaExtractorCompat, a new class that provides equivalent features to platform MediaExtractor.
  • Add experimental 'ExoPlayer' pre-warming support for playback usingMediaCodecVideoRenderer. You can configure DefaultRenderersFactory through experimentalSetEnableMediaCodecVideoRendererPrewarming to provide a secondary MediaCodecVideoRenderer to ExoPlayer. If enabled, ExoPlayer pre-processes the video of consecutive media items during playback to reduce media item transition latency.
  • Reduce default values for bufferForPlaybackMs and bufferForPlaybackAfterRebufferMs in DefaultLoadControl to 1000 and 2000 ms respectively.
  • Initialize DeviceInfo and device volume asynchronously (if enabled using setDeviceVolumeControlEnabled). These values aren't available instantly after ExoPlayer.Builder.build(), and Player.Listener notifies changes through onDeviceInfoChanged and onDeviceVolumeChanged.
  • Initial audio session id is no longer immediately available after creating the player. You can use AnalyticsListener.onAudioSessionIdChanged to listen to the initial update if required.
  • Consider language when selecting a video track. By default, select a 'main' video track that matches the language of the selected audio track, if available. Explicit video language preferences can be expressed with TrackSelectionParameters.Builder.setPreferredVideoLanguage(s).
  • Add selectedAudioLanguage parameter to DefaultTrackSelector.selectVideoTrack() method.
  • Add retryCount parameter to MediaSourceEventListener.onLoadStarted and corresponding MediaSourceEventListener.EventDispatcher methods.
  • Fix bug where playlist items or periods in multi-period DASH streams with durations that don't match the actual content could cause frame freezes at the end of the item (#1698).
  • Move BasePreloadManager.Listener to a top-level PreloadManagerListener.
  • RenderersFactory.createSecondaryRenderer can be implemented to provide secondary renderers for pre-warming. Pre-warming enables quicker media item transitions during playback.
  • Enable sending CmcdData for manifest requests in adaptive streaming formats DASH, HLS, and SmoothStreaming (#1951).
  • Provide MediaCodecInfo of the codec that will be initialized in MediaCodecRenderer.onReadyToInitializeCodec (#1963).
  • Change AdsMediaSource to allow the AdPlaybackStates to grow by appending ad groups. Invalid modifications are detected and throw an exception.
  • Fix issue where additional decode-only frames may be displayed in quick succession when transitioning to content media after a mid-roll ad.
  • Make DefaultRenderersFactory add two MetadataRenderer instances to enable apps to receive two different schemes of metadata by default.
  • Reevaluate whether the ongoing load of a chunk should be cancelled when playback is paused (#1785).
  • Add option to ClippingMediaSource to allow clipping in unseekable media.
  • Fix bug where seeking with pre-warming could block following media item transition.
  • Fix a bug where ExoPlayer.isLoading() remains true while it has transitioned to STATE_IDLE or STATE_ENDED (#2133).
  • Add lastRebufferRealtimeMs to LoadControl.Parameter (#2113).
• Transformer:
  • Add support for transmuxing into alternative backward compatible formats.
  • Add support for transcoding and transmuxing Dolby Vision (profile 8) format.
  • Update parameters of VideoFrameProcessor.registerInputStream and VideoFrameProcessor.Listener.onInputStreamRegistered to use Format.
  • Generate HDR static metadata when using DefaultEncoderFactory.
  • Enable support for Android platform diagnostics using MediaMetricsManager. Transformer forwards editing events and performance data to the platform, which helps to provide system performance and debugging information on the device. This data may also be collected by Google if sharing usage and diagnostics data is enabled by the user of the device. Apps can opt-out of contributing to platform diagnostics for Transformer with Transformer.Builder.setUsePlatformDiagnostics(false).
  • Split InAppMuxer into InAppMp4Muxer and InAppFragmentedMp4Muxer. You use InAppMp4Muxer to produce a non-fragmented MP4 file, while InAppFragmentedMp4Muxer is for producing a fragmented MP4 file.
  • Move Muxer interface from media3-muxer to media3-transformer.
  • Add MediaProjectionAssetLoader, which provides media from a MediaProjection for screen recording, and add support for screen recording to the Transformer demo app.
  • Add #getInputFormat() to Codec interface.
  • Shift the responsibility to release the GlObjectsProvider onto the caller in DefaultVideoFrameProcessor and DefaultVideoCompositor when possible.
• Extractors:
  • AVI: Fix handling of files with constant bitrate compressed audio where the stream header stores the number of bytes instead of the number of chunks.
  • Fix handling of NAL units with lengths expressed in 1 or 2 bytes (rather than 4).
  • Fix ArrayIndexOutOfBoundsException in MP4 edit lists when the edit list starts at a non-sync frame with no preceding sync frame (#2062).
  • Fix issue where TS streams can get stuck on some devices (#2069).
  • FLAC: Add support for 32-bit FLAC files. Previously these would fail to play with IllegalStateException: Playback stuck buffering and not loading (#2197).
• Audio:
  • Fix onAudioPositionAdvancing to be called when playback resumes (previously it was called when playback was paused).
  • Don't bypass SonicAudioProcessor when SpeedChangingAudioProcessor is configured with default parameters.
  • Fix underflow in Sonic#getOutputSize() that could cause DefaultAudioSink to stall.
  • Fix MediaCodecAudioRenderer.getDurationToProgressUs() and DecoderAudioRenderer.getDurationToProgressUs() so that seeks correctly reset the provided durations.
  • Make androidx.media3.common.audio.SonicAudioProcessor final.
  • Add support for float PCM to ChannelMappingAudioProcessor and TrimmingAudioProcessor.
• Video:
  • Change MediaCodecVideoRenderer.shouldUsePlaceholderSurface to protected so that applications can override to block usage of placeholder surfaces (#1905).
  • Add experimental ExoPlayer AV1 sample dependency parsing to speed up seeking. Enable it with the new DefaultRenderersFactory.experimentalSetParseAv1SampleDependencies API.
  • Add experimental ExoPlayer API to drop late MediaCodecVideoRenderer decoder input buffers that are not depended on. Enable it with DefaultRenderersFactory.experimentalSetLateThresholdToDropDecoderInputUs.
  • Fix issue where a player without a surface was ready immediately and very slow decoding any pending frames (#1973).
  • Exclude Xiaomi and OPPO devices from detached surface mode to avoid screen flickering (#2059).
• Text:
  • Add support for VobSub subtitles (#8260).
  • Stop eagerly loading all subtitle files configured with MediaItem.Builder.setSubtitleConfigurations, and instead only load one if it is selected by track selection (#1721).
  • TTML: Add support for referencing tts:origin and tts:extent using style (#2953).
  • Restrict WebVTT and SubRip timestamps to exactly 3 decimal places. Previously we incorrectly parsed any number of decimal places but always assumed the value was in milliseconds, leading to incorrect timestamp (#1997).
  • Fix playback hanging when a playlist contains clipped items with CEA-608 or CEA-708 captions.
  • Fix IllegalStateException when an SSA file contains a cue with zero duration (...

  • Upgrade Kotlin from 1.9.20 to 2.0.20 and use Compose Compiler Gradle
    plugin. Upgrade KotlinX Coroutines library from 1.8.1 to 1.9.0.
• ExoPlayer:
  • Initial audio session id is no longer immediately available after
    creating the player. You can use
    AnalyticsListener.onAudioSessionIdChanged to listen to the initial
    update if required.

    DefaultRenderersFactory.experimentalSetLateThresholdToDropDecoderInputUs.
• Session:
  • Keep foreground service state for an additional 10 minutes when playback
    pauses, stops or fails. This allows users to resume playback within this
    timeout without risking foreground service restrictions on various
    devices. Note that simply calling player.pause() can no longer be used
    to stop the foreground service before stopSelf() when overriding
    onTaskRemoved, use MediaSessionService.pauseAllPlayersAndStopSelf()
    instead.
  • Make MediaSession.setSessionActivity(PendingIntent) accept null
    (#2109).
  • Keep notification visible when playback enters an error or stopped
    state. The notification is only removed if the playlist is cleared or
    the player is released.
  • Improve handling of Android platform MediaSession actions ACTION_PLAY
    and ACTION_PAUSE to only set one of them according to the available
    commands and also accept if only one of them is set.
• Remove deprecated symbols:
  • Removed the following deprecated DownloadHelper methods:
    • Constructor DownloadHelper(MediaItem, @Nullable MediaSource, TrackSelectionParameters, RendererCapabilities[]), use
      DownloadHelper(MediaItem, @Nullable MediaSource, TrackSelectionParameters, RendererCapabilitiesList) instead.
    • getRendererCapabilities(RenderersFactory), equivalent
      functionality can be achieved by creating a
      DefaultRendererCapabilitiesList with a RenderersFactory, and
      calling DefaultRendererCapabilitiesList.getRendererCapabilities().
  • Removed
    PlayerNotificationManager.setMediaSessionToken(MediaSessionCompat)
    method. Use
    PlayerNotificationManager.setMediaSessionToken(MediaSession.Token) and
    pass in (MediaSession.Token) compatToken.getToken()instead.

1.5.1

This release includes the following changes since the 1.5.0 release:

• ExoPlayer:
  • Disable use of asynchronous decryption in MediaCodec to avoid reported codec timeout issues with this platform API (#1641).
• Extractors:
  • MP3: Don't stop playback early when a VBRI frame's table of contents doesn't cover all the MP3 data in a file (#1904).
• Video:
  • Rollback of using MediaCodecAdapter supplied pixel aspect ratio values when provided while processing onOutputFormatChanged (#1371).
• Text:
  • Fix bug in ReplacingCuesResolver.discardCuesBeforeTimeUs where the cue active at timeUs (started before but not yet ended) was incorrectly discarded (#1939).
• Metadata:
  • Extract disc/track numbering and genre from Vorbis comments into MediaMetadata (#1958).

1.5.0

This release includes the following changes since the 1.4.1 release:

• Common Library:
  • Add ForwardingSimpleBasePlayer that allows forwarding to another player with small adjustments while ensuring full consistency and listener handling (#1183).
  • Replace SimpleBasePlayer.State.playlist by getPlaylist() method.
  • Add override for SimpleBasePlayer.State.Builder.setPlaylist() to directly specify a Timeline and current Tracks and Metadata instead of building a playlist structure.
  • Increase minSdk to 21 (Android Lollipop). This is aligned with all other AndroidX libraries.
  • Add androidx.media3:media3-common-ktx artifact which provides Kotlin-specific functionality built on top of the Common library
  • Add Player.listen suspending extension function to spin a coroutine to listen to Player.Events to the media3-common-ktx library.
  • Remove @DoNotInline annotations from manually out-of-lined inner classes designed to avoid runtime class verification failures. Recent versions of R8 now automatically out-of-line calls like these to avoid the runtime failures (so the manual out-of-lining is no longer required). All Gradle users of the library must already be a using a version of the Android Gradle Plugin that uses a version of R8 which does this, due to compileSdk = 35. Users of the library with non-Gradle build systems will need to ensure their R8-equivalent shrinking/obfuscating step does a similar automatic out-of-lining process in order to avoid runtime class verification failures. This change has already been done in other AndroidX libraries.
• ExoPlayer:
  • MediaCodecRenderer.onProcessedStreamChange() can now be called for every media item. Previously it was not called for the first one. Use MediaCodecRenderer.experimentalEnableProcessedStreamChangedAtStart() to enable this.
  • Add PreloadMediaSource.PreloadControl.onPreloadError to allow PreloadMediaSource.PreloadControl implementations to take actions when error occurs.
  • Add BasePreloadManager.Listener to propagate preload events to apps.
  • Allow changing SNTP client timeout and retry alternative addresses on timeout (#1540).
  • Remove MediaCodecAdapter.Configuration.flags as the field was always zero.
  • Allow the user to select the built-in speaker for playback on Wear OS API 35+ (where the device advertises support for this).
  • Defer the blocking call to Context.getSystemService(Context.AUDIO_SERVICE) until audio focus handling is enabled. This ensures the blocking call isn't done if audio focus handling is not enabled (#1616).
  • Allow playback regardless of buffered duration when loading fails (#1571).
  • Add AnalyticsListener.onRendererReadyChanged() to signal when individual renderers allow playback to be ready.
  • Fix MediaCodec.CryptoException sometimes being reported as an "unexpected runtime error" when MediaCodec is operated in asynchronous mode (default behaviour on API 31+).
  • Pass bufferedDurationUs instead of bufferedPositionUs with PreloadMediaSource.PreloadControl.onContinueLoadingRequested(). Also changes DefaultPreloadManager.Status.STAGE_LOADED_TO_POSITION_MS to DefaultPreloadManager.Status.STAGE_LOADED_FOR_DURATION_MS, apps then need to pass a value representing a specific duration from the default start position for which the corresponding media source has to be preloaded with this IntDef, instead of a position.
  • Add ForwardingRenderer implementation that forwards all method calls to another renderer (1703).
  • Add playlist preloading for the next item in the playlist. Apps can enable preloading by calling ExoPlayer.setPreloadConfiguration(PreloadConfiguration) accordingly. By default preloading is disabled. When opted-in and to not interfere with playback, DefaultLoadControl restricts preloading to start and continue only when the player is not loading for playback. Apps can change this behaviour by implementing LoadControl.shouldContinuePreloading() accordingly (like when overriding this method in DefaultLoadControl). The default implementation of LoadControl disables preloading in case an app is using a custom implementation of LoadControl.
  • Add method MediaSourceEventListener.EventDispatcher.dispatchEvent() to allow invoking events of subclass listeners (1736).
  • Add DefaultPreloadManager.Builder that builds the DefaultPreloadManager and ExoPlayer instances with consistently shared configurations.
  • Remove Renderer[] parameter from LoadControl.onTracksSelected() as DefaultLoadControl implementation can retrieve the stream types from ExoTrackSelection[].
  • Deprecated DefaultLoadControl.calculateTargetBufferBytes(Renderer[], ExoTrackSelection[]) and marked method as final to prevent overrides. The new DefaultLoadControl.calculateTargetBufferBytes(ExoTrackSelection[]) should be used instead.
  • Report MediaSourceEventListener events from secondary sources in MergingMediaSource. This will result in load start/error/cancelled/completed events being reported for sideloaded subtitles (those added with MediaItem.LocalConfiguration.subtitleConfigurations), which may appear as duplicate load events emitted from AnalyticsListener.
  • Prevent subtitle & metadata errors from completely stopping playback. Instead the problematic track is disabled and playback of the remaining tracks continues (#1722).
    • In new subtitle handling (during extraction), associated parse (e.g. invalid subtitle data) and load errors (e.g. HTTP 404) are emitted via onLoadError callbacks.
    • In legacy subtitle handling (during rendering), only associated load errors are emitted via onLoadError callbacks while parse errors are silently ignored (this is pre-existing behaviour).
  • Fix bug where playlist items or periods in multi-period DASH streams with durations that don't match the actual content could cause frame freezes at the end of the item (#1698).
  • Add a setter to SntpClient to set the max elapsed time since the last update after which the client is re-initialized (#1794).
• Transformer:
  • Add SurfaceAssetLoader, which supports queueing video data to Transformer via a Surface.
  • ImageAssetLoader reports unsupported input via AssetLoader.onError instead of throwing an IllegalStateException.
  • Make setting the image duration using MediaItem.Builder.setImageDurationMs mandatory for image export.
  • Add export support for gaps in sequences of audio EditedMediaItems.
• Track Selection:
  • DefaultTrackSelector: Prefer object-based audio over channel-based audio when other factors are equal.
• Extractors:
  • Allow Mp4Extractor and FragmentedMp4Extractor to identify H264 samples that are not used as reference by subsequent samples.
  • Add option to enable index-based seeking in AmrExtractor.
  • Treat MP3 files with more than 128kB between valid frames as truncated (instead of invalid). This means files with non-MP3 data at the end, with no other metadata to indicate the length of the MP3 bytes, now stop playback at the end of the MP3 data instead of failing with ParserException: Searched too many bytes.{contentIsMalformed=true, dataType=1} (#1563).
  • Fix preroll sample handling for non-keyframe media start positions when processing edit lists in MP4 files (#1659).
  • Improved frame rate calculation by using media duration from the mdhd box in Mp4Extractor and FragmentedMp4Extractor (#1531).
  • Fix incorrect scaling of media_time in MP4 edit lists. While segment_duration was already correctly scaled using the movie timescale, media_time is now properly scaled using the track timescale, as specified by the MP4 format standard (#1792).
  • Handle out-of-order frames in endIndices calculation for MP4 with edit list (#1797).
  • Fix media duration parsing in mdhd box of MP4 files to handle -1 values (#1819).
  • Add support for identifying h263 box in MP4 files for H.263 video (#1821).
  • Add AC-4 Level-4 ISO base media file format support (#1265).
• DataSource:
  • Update HttpEngineDataSource to allow use starting at version S extension 7 instead of API level 34 (#1262).
  • DataSourceContractTest: Assert that DataSource.getUri() returns the resolved URI (as documented). Where this is different to the requested URI, tests can indicate this using the new DataSourceContractTest.TestResource.Builder.setResolvedUri() method.
  • DataSourceContractTest: Assert that DataSource.getUri() and getResponseHeaders() return their 'open' value after a failed call to open() (due to a...
